A calculator is required. A formula packet equivalent to the standard AP

“Half-back” test interview
session schedule is listed below. If you do the world’s best test corrections
(on separate sheets of paper, with clear labeling, clear work, and a clear
sense of how you have corrected your misunderstandings) and show them to Mr. Hansen in person and pass a short oral and/or written confidence assessment
administered by Mr. Hansen, you will earn back half the points you lost on
the 12/3 test. If your entire class does an admirable job with the
corrections and interviews, the adjustment will be somewhat more generous. Warning: Since the test was not
comprehensive (since that would have been impossible), questions on the
confidence assessment may draw from closely related topics that were not
covered on the test itself. For example, you may be required to compute binomial
probabilities or find the s.d. of a random variable
(don’t forget the Stat Calc 1 L1,L2 shortcut).
The objective is to learn the material solidly. Ideally, this should happen
before the test, but as the saying goes, better late than never.

HW due (both periods):
1. Please reply to the e-mail(s) in your inbox!
2. Work on your test corrections, and make sure that all your previously
assigned HW is complete, correct, and neat. If time permits, an answer key
for some of the problems will be posted this weekend on hwstore.org.

HW due (both periods):
Write, in your own words and using
grammatically correct, complete sentences, what is meant by the standard error
of the sample proportion. Include in your paragraph answers to the following
questions, at a minimum: (1) What does it really mean? (2) How is it useful?
(3) Who cares about it every October and November, and why? Don’t bother to
answer the question of how it is calculated, since we have a formula for
that.
Period 3 class as usual.
Field trip to Pew Research Center. Be in school dress (required), and
assemble on the service road near the Martin Gym. Bus will depart STA
shortly after 9:10 a.m., which is the start of period 4. Please be prompt.
We’ll wait a few minutes for students coming from NCS, but we can’t wait too
long, since we have to be downtown for a presentation that begins at 10:00.
We will be back on campus before period 5 starts at 11:55 a.m. You will miss
your period 4 class, chapel, ensemble, and part of period 5 lab. The
following students will be excused:
Period 3: A.J., Charles, Chris H., Chris K., Daniel, Isaac, Jim, John F.,
John H., Jordan, R.J., Will K. ()
Period 4: Alex, Andrew, Frank, Graham, Jack, Nelson (), Roy, Ruslan, Vincent,
Warren, Will T.

a sketch of it in your HW paper, and describe some of the conclusions you can
draw from it.

Period 3 HW due: Prepare
for a quiz, or possibly a double quiz, covering the first 2 pages of the AP
formula sheet. You can view pages 12 and 13 from the 2010 AP Statistics
Course Description (downloadable from link under “Essential Links” section
below) if you wish. Note: For
technical reason, pages 12 and 13 need to be requested as pages 16 and 17 if
you print them from your computer.
In class: Review for Wednesday’s test. If you’re not in class today, don’t
panic—you already know everything you need to know, and if you survived the
“half back” corrections challenge, you’re in better shape now than you were
before the 12/3 test.
Period 4: No class.

Test (100 pts.), on all material, year to date, with
special emphasis on probability, random variables, the sampling distributions
of and , and the CLT.
This will be the last major assessment of the quarter. There are a large
number of tests scheduled for today, but fortunately, of the 243 students who
have tests today, only 5 have a test in one of Mr. Hansen’s classes. Nobody
has a double conflict with Mr. Hansen. It originally looked as if no dates
would be possible for a test before the new year because of scheduling
conflicts, but amazingly, all the stars aligned on 12/17.
Some questions will be recycled (with small changes) from the 12/3 test.
Other questions may cover areas that we have either not seen in a long time
or did not have a chance to include on the earlier test.
Partial study guide:
1. Make sure you know all your terminology and notation cold. Seriously, terminology and notation are half the battle.
Flash cards may help.
2. We haven’t made any residual plots in quite a long time. You need to make
sure you still know how to make residual plots, and you need to know how to
interpret various shapes of residual plots (e.g., bowl-shaped or dome-shaped)
and draw suitable conclusions.
3. Not every distribution is binomial, geometric, or normal. Make sure you
know how to talk intelligently about any
type of distribution, how to compute means and variances for any random
variable that is thrown at you, and how to use the correct notation to refer
to it all.
4. Sampling distributions are the key to the entire remainder of the course.
By now you should be starting to speak intelligently about sampling
distributions, especially the sampling distributions of and .
5. While it is true that you don’t need to spend much time memorizing
formulas, you need to know cold
what each formula on the first 2 pages of the AP formula sheet means. For
example, the formula npq
for the variance of a binomial random variable does you no good if you don’t
know how to recognize a binomial random variable when you encounter it.
6. There may be a couple of questions related to the Pew Research Center
field trip. If you were not on the field trip, make sure you get a short
debrief from someone who was there. These questions will not contribute a
significant number of points to the total.
7. The following terms are among those that have “special meaning” that
differs from the common, popular definition: statistic, parameter, experiment, bias, confidence, probability,
correlation, random, normal, and significance.
You should know all the STAtistics definitions.
Example: In the rest of the world, “significance” means size, importance, relevance,
or magnitude. In our world, it means a difference that is too large to be
plausibly explained by chance alone.
